Abstract
The once-application compound weedicide for seedling bed and direct seeding bed includes a certain quantity of thiocarbamate weedicide youkehai, sulfonylurea weedicide bensulfuron, surfactant dispersing agent, wetting agent and solid carrier.
Description
The invention belongs to the weed killer herbicide field, relate in particular to the disposable composite weeding wetting powder that use in a kind of raising rice seedlings and live field.
Bensulfuron-methyl and Youkebai are widely-used in agricultural chemicals, all having introduced with the bensulfuron-methyl as Chinese patent application CN 1069392, CN 1096920 etc. is the weed killer herbicide of active constituent, Youkebai 50% missible oil of Mitsubishi oiling has been realized commercialization, but carries out composite do not see as yet bibliographical information and application both at home and abroad with bensulfuron-methyl and Youkebai; According to the investigation that each paddy rice producing region herbicides for use in paddy of China is used and the retrieval of relevant department, at present can be effective in raising rice seedlings and live field prevent and kill off the complex preparation of grassy weed, sedge weed and broad leaved weed simultaneously, still belong to blank, used unitary agent, the effect of the artificial mixture preparation management of weeds that mixes is undesirable in the application, mu cost height.
The object of the present invention is to provide a kind of raising rice seedlings and direct seeding fields herbicidal new varieties, efficient, low toxicity, low content, low cost, and can prevent and kill off grassy weed, sedge weed and broad leaved weed simultaneously in effective.
Preparation of the present invention is:
A kind of herbicides for use in paddy contains the thioamino-formates weed killer herbicide Youkebai at paddy field application by throwing them, and sulfonylurea herbicide bensulfuron-methyl and filling surface activating agent thereof, wetting agent, diffusant is characterized in that containing:
Youkebai, s-(α, α-Er Jiajibianji) piperidines-1-thiol formic acid esters 1-100 part
Bensulfuron-methyl, α-(4,6-dimethoxypyridin-2-base carbamyl amino
Sulfonyl)-neighbour-toluic acid 0.1-10 part
Surfactant 1-10 part
Diffusant 1-6 part
Wetting agent 0.1-5 part
Solid carrier 1-50 part
Described surfactant is one or more in alpha-alkene sulfonate, higher alcohol sulfate, non-ionic surfactant polyoxyethylene nonyl phenylate, polyoxyethylene oleoyl ether, polyoxyethylene oleate, PEP-101, polyoxyethylene fatty acid ester, Arlacel-80, sorbitan monolaurate, the styryl phenol polyethenoxy polyethenoxy ether.
Described diffusant is one or more in sodium lignin sulfonate, di-2-ethylhexylphosphine oxide (benzyl naphthalene sodium sulfonate), di-2-ethylhexylphosphine oxide (novalgin), the sodium metnylene bis-naphthalene sulfonate.
Described wetting agent is one or more in lauryl sodium sulfate, neopelex, alkyl butyric acid sulfonate, alkyl phosphoric acid sodium, carboxylate, alkylphenol-polyethenoxy base ether, the polyoxyethylene poly-oxygen propylene aether block thing.
Described solid carrier is one or more in kaolin, talcum powder, potter's clay, diatomite, bentonite, the silica.
One-time rice sprout-cultivating of the present invention and direct seeding field mixed herbicide, its production method is: earlier with the herbicidal activity component be crushed to the 1-44 micron after surfactant, wetting agent, diffusant and carrier fully mix by a certain percentage, pack then, the gained preparation is the bulky powder shape.This production method can be suitable conversion weed killer herbicide kind and being easy to consider the change of filling a prescription.
The using method of one-time rice sprout-cultivating of the present invention and direct seeding field mixed herbicide: this powder is raising rice seedlings and live field weeding wetting powder, prevent and kill off half dry nursery weeds and convert 50 kilograms of even spraying of water with every mu of commodity amount 200 gram, early rice can be prior to seeding or same day to 7 day after planting in; Late rice dispenser in same day to two day prior to seeding or after planting; Live field: before the sowing or dispenser in same day to two day after planting.
The characteristics of preparation of the present invention be to use convenience, weeding ratio height, broad weed-killing spectrum, toxicity low, to a kind of complex preparation of crop safety, its drug effect that is used for raising rice seedlings and the weeding of live field is shown in table 1-table 3, and herbicide formulations of the present invention is called " young standing grain luxuriant growth " in table.
Below be embodiments of the invention:
